This is basically quite funny but it does have some puzzling elements.

1. I've never heard of Nunavut and, although I was able to pause my reading of the sketch in order to Google it, I wouldn't have been happy to do that while watching it performed on TV.

2. A caravan load of polar bears? That's a puzzling expression because a caravan in normal English usage is a little house on wheels that is pulled behind a car. There's no way polar bears could travel in a caravan without human assistance and, even so, you wouldn't get many in a caravan. Of course, a caravan can also be a convoy (which makes a lot more sense in this context) but a caravan "load" does strongly suggest we're talking about the little house on wheels. Even if you delete "load", the vast majority of viewers will still imagine the little house on wheels.

3. I'm not sure what is meant by "the base" swallowing the story. In context, I assume it means the American people (the electoral base?) but, on first hearing, I was put in mind of an army base.

4. I didn't immediately understand why the base should be unhappy that the polar bears are white. After some thought, I decided they were unhappy because white creatures were being denied access to the USA whereas, under strict immigration policy, it's usually non-whites that are kept out. If I'm right, it's a funny line once you understand it, but it's not immediately understandable.

5. Lastly, there is absolutely no way you can say "faggots" in Trump's last line without causing massive offence to millions of people who were previously enjoying the sketch. The correct word to use in that last line is "pussies".

Rood1) You're spot on Nunavat is too obscure, I was probably trying to be a smart arse ( I am prone to this)2) The caravan is what he cites as the movement of migrants3)The Base is what they call his followers4) The Base is also seen as containing a lot of right wing racists, the aim being they like white bears and dislike black bears5) As for Faggots/ Pussies the same people would be offended .This could be down to me watching way too much American news as it may have bastardized my sketch.But as always I love the fact that you take time to read and offer advice as in the main its spot on, I think this one failed as it was more for a CNN viewer than anything.But once again thanks for the read and the feedback as it keeps me in check .
